Wheel size question

'This tire and wheel combination works perfectly! When sat side by side, they are the same height.'
There are some other things that come into the equation like slippage and tyre profile that can make the situation unpredictable. I always used triangular Dunlops on my old racer, until I respoked the wheels, and then used a flatter profile. It stuffed the handling. That model of commando with the very responsive steering must still be around, the safety of changing tyres would be very marginal. I think it really depends on what you are doing with the bike. If it is always used on smooth roads and never thrashed, it's unlikely to grab you by the throat. I recenly had a Yamaha rd250 which was fitted with the prescribed tyres. Our roads tend to get a slight high spot running along them in the direction of travel. I'm used to riding aroung bad handling, but this one gave me all the messages. I really did not like the way it felt.

Acotrel you keep mentioning the "decent handling" Cdo model but say its was too dangerous for public consumption. This does not compute to me, how can a better handling bike be a more dangerous one?

So,

The new rubber is on the bike since yesterday.
Although I am still running them in, and before doing anything much with them, I can report my Roadster is simply a different bike. So much more sure footed in moderate motorway and city traffic

Most important of all, the weave / oscillation experienced before at over 100 Km/h, is completely gone increasing confidence hugely.

A good investment I think, and looking forward to many happy Kms.

In fairness, according to the guy at the tire shop, my Avons were manufactured in 11/1998 (hard to believe) !!!

New to this forum but have owned my MK3 since new. I have found it quite sensitive to chain/wheel alignment in regard to high speed weave. As I recall this started out as a weave, then got worse, then when just trying slow down enough to stay alive it would almost turn into a tank slapper before it stopped! All this was because of rear wheel alignment, and possibly not helped by the narrow 8" rise handlebars I had to have in 1975.

What tyre pressures should I go with my new Batlax ribber.
Any suggestions?
Cheers, Aris

Recommended pressures , then up it a pound or 2.
